Indicates a potentially hazardous situation which, if not avoided, will result in minor or moderate injury, or may result in serious injury or death. Additionally there may be significant property damage. FLOW OF OPERATION BASIC SETUP Meanings of Alert Symbols The following alert symbols are used in this manual. MAIN APPLICATIONS & SETTING METHODS Height Steps and Warpage Double Sheet Detection Indicates the possibility of laser radiation. Indicates prohibition when there is a risk of minor injury from electrical shock or other source if the product is disassembled. Thickness Positioning Eccentricity and Surface Deflection DETAILED SETTINGS TROUBLESHOOTING SPECIFICATIONS INDEX SETTING TRANSITION CHARTS 8 ZX2 User’s Manual Laser Safety Sensor Head ZX2-LD50L, LD50, LD100L, LD100: Class 2 CONTENTS INTRODUCTION PREPARATION FOR MEASUREMENT Never look into the laser beam. Doing so continuously will result in visual impairment. FLOW OF OPERATION BASIC SETUP Do not disassemble the product. Doing so may cause the laser beam to leak, resulting in the danger of visual impairment. MAIN APPLICATIONS & SETTING METHODS Height Steps and Warpage Sensor Head ZX2-LD50V: Class 1 Double Sheet Detection Thickness Positioning Do not disassemble the product. Doing so may cause the laser beam to leak, resulting in the danger of visual impairment. Eccentricity and Surface Deflection DETAILED SETTINGS TROUBLESHOOTING SPECIFICATIONS INDEX SETTING TRANSITION CHARTS ZX2 User’s Manual 9 CONTENTS In Europe, diffuse-reflective models in the ZX2 Series are categorized as Class 2 laser products and the regular-reflective model is classified as a Class 1 laser product according to EN60825-1 (see note). The CE markings on the products also reflect these categorizations. INTRODUCTION PREPARATION FOR MEASUREMENT FLOW OF OPERATION BASIC SETUP MAIN APPLICATIONS & SETTING METHODS Height Steps and Warpage Double Sheet Detection Thickness Positioning Eccentricity and Surface Deflection DETAILED SETTINGS TROUBLESHOOTING SPECIFICATIONS In the U.S.A., diffuse-reflective models in the ZX2 Series are categorized as Class II laser products, and the regular-reflective model is classified as a Class I laser product according to EN60825-1 criteria, in accordance with the stipulations of the FDA standard Laser Notice No. 50 (see note). The diffuse-reflective models have already been registered with the CDRH (Center for Devices and Radiological Health). (Accession Number: 1020665-000) Place the laser warning label and the FDA label on the sensor. The regular-reflective model is scheduled for registration with CDRH. Place the laser warning label on the sensor. The ZX2 Series is meant to be built into final system equipment. Pay special attention to the following precautions for the safe use of the product: Note: Europe: Class 1 and Class 2 of EN 60825-1: 1994 +A11:1996 +A2:2001 = IEC 60825-1:1993 +A1:1997 +A2:2001 U.S.A.: Class I and Class II of FDA (21 CFR1040.10) (1) ZX2-LD emits visual laser beam. Do not stare directly into the laser. Make sure that the laser beam path is terminated. If specular objects are present in the laser beam path, make sure that they are prevented from reflecting the laser beam. When used without an enclosure, make sure the laser path from eye level is avoided. (2) To avoid exposure to hazardous laser radiation, do not displace nor remove the protective housing during operation, maintenance, and any other servicing. (3) As for countries other than those of Europe and the U.S.A., observe the regulations and standards specified by each country. (4) Label Indications The EN and FDA labels are supplied with the product. Replace the current labels with them according to the instructions given in the manuals. INDEX SETTING TRANSITION CHARTS 10 ZX2 User’s Manual Precautions for Safe Use Please observe the following precautions for safe use of the products. Installation Environment • Do not use the product in environments where it can be exposed to inflammable/ explosive gas. • Do not install the product close to high-voltage devices and power devices in order to secure the safety of operation and maintenance. CONTENTS INTRODUCTION PREPARATION FOR MEASUREMENT FLOW OF OPERATION Power Supply and Wiring • The supply voltage must be within the rated range (DC12 to 24 V±10%). • Reverse connection of power supply is not allowed. Connection to AC power supply is also not allowed. • Open-collector outputs should not be short-circuited. • High-voltage lines and power lines must be wired separately from this product. Wiring them together or placing in the same duct may cause induction, resulting in malfunction or damage. • Always turn off the power supply before connecting or disconnecting cables and connectors. Others • Do not attempt to dismantle, repair, or modify the product. • Dispose of this product as industrial waste.

ZX2 User’s Manual Warming Up After turning ON the power supply, allow the product to stand for at least 10 minutes before use. The circuits are still unstable just after the power supply is turned ON, so measured values may fluctuate gradually. A warmup of at least 10 minutes is also required after canceling LD-OFF input if LDOFF input is being used. Sensing Object The product cannot accurately measure the following types of objects: Transparent objects, objects with an extremely low reflective sensor ratio, objects smaller than the beam size, objects with a large curvature, excessively inclined objects, etc. Mutual Interference Inserting a calculating unit between amplifier units can prevent mutual interference between two sensor heads. CONTENTS INTRODUCTION PREPARATION FOR MEASUREMENT FLOW OF OPERATION BASIC SETUP MAIN APPLICATIONS & SETTING METHODS Height Maintenance • Always turn OFF the power supply before adjusting or connecting/disconnecting the sensor head. • Do not use thinner, benzene, acetone or kerosene to clean the sensor head and amplifier units. If large dust particles adhere to the front filter of the sensor head, use a blower brush (used to clean camera lenses) to blow them off. Do not blow the dust away with your mouth. To remove smaller dust particles, use a soft cloth (for lenses) with a small amount of alcohol. Take care not to wipe them off with excessive force. Scratches on the filter may cause errors.

Important • The minimum display value is –99.999, and the maximum display value is 999.999. If the measured value is below the minimum value after execution of zero reset, –99.999 will be displayed. 999.999 will be displayed if the measured value is above the maximum value. Zero reset can be executed only if the measured value is within ±10% of the rated measurement range. • Even if a zero reset is executed, the threshold does not change from the setting before execution of the zero reset. (For example, even if a zero reset is executed so that the measured value 2 becomes 0, the HIGH threshold stays at 5 if it is 5 before zero reset is executed.) • After a zero reset, analog values are output in a range that corresponds to the zero-reset display value (initial value: 0 mm), which accords with the zero-reset distance point. (When the zero-reset display is 0 mm and scaling is set to OFF, the analog output value will be 3 V if Positioning Eccentricity and Surface Deflection DETAILED SETTINGS the range is 1 to 5 V, 0 V if the range is –5 to 5 V, and 12 mA if the range is 4 to 20 mA.)

ZX2 User’s Manual Reference: Distance between two diffusereflective models that causes malfunction when mutual interference prevention is turned off The distance at which the resolution exceeded the rated value when sensors were moved towards each other (in all the X, Y, and Z directions) while mutual interference prevention was turned off was measured. (Workpiece: white ceramic; positioned facing the sensor, not on an angle.) Horizontal direction Vertical direction CONTENTS INTRODUCTION PREPARATION FOR MEASUREMENT FLOW OF OPERATION BASIC SETUP MAIN APPLICATIONS & SETTING METHODS Height Steps and Warpage Results: For all models, the distance that causes malfunction is 0 mm in all the X, Y, and Z directions. Double Sheet Detection Thickness Note. The above result was obtained when the white ceramic workpiece was positioned facing the sensor, not on an angle. Note that mutual interference can occur when using different types of workpieces or when the sensors are attached at an angle, so it is recommended to use the sensors with mutual interference prevention turned on.
